(a)
Fraction of the people that are adults =
58 Fraction of the adults that are men =
35 Fraction of the people that are men
=
58 x
35 =
38 (b)
Total number of hashbrowns
= (3 u x 3) + (5 u x 1)
= 9 u + 5 u
= 14 u
14 u = 168
1 u = 168 ÷ 14 = 12
Number of adults
= 2 u + 3 u
= 5 u
= 5 x 12
= 60
Answer(s): (a)
38; (b) 60
